now,
substituting the result in the original equation, we get
⇒
or
⇒ 2a =
or
⇒ 2a = 4
or
a = 2
Answer:
x =
Step-by-step explanation:
Distribute parenthesis on both sides of the equation.
3x - 3 - 4x - 2 = 8x - 8 ← simplify left side
- x - 5 = 8x - 8 ( subtract 8x from both sides )
- 9x - 5 = - 8 ( add 5 to both sides )
- 9x = - 3 ( divide both sides by - 9 )
x = = =
That's a very interesting question.
Here's the way I thought about it, and the answer I came up with
while avoiding the need to define and count every possible outcome:
-- There are (2 x 2 x 2 x 2) = 16 possible outcomes of 4 flips.
-- There are several different ways to get 1 heads and 3 tails.
-- There are several different ways to get 2 heads and 2 tails.
-- There are several different ways to get 3 heads and 1 tails.
-- But there's only one way to get heads all 4 times,
and there's only one way to get tails all 4 times.
-- So there are 2 ways for all 4 flips to produce the same face.
The probability of that is 2/16 = 1/8 = 12.5% , and I'm saying
that this is the least probable result of 4 flips.
Answer:
4/10 or 2/5 if you need to simplify
The equation where y is the cost in month x. This equation represents the situation.
Step-by-step explanation:
Step 1:
The service charges for the first month = $72.99,
The service charges for the second month = $101.44, and
The service charges for the third month = $129.89.
The difference between the first and the second month = $28.45.
The difference between the second and the third month = $28.45.
So for every consecutive month, the service charges increase by $28.45.
Step 2:
The service charges are always added on to the first month's charges i.e. $72.99.
So the equation to represent the situation is where x is the month in which we are calculating that months charges y.
If x = 1,
if x = 2,
If x = 3,
So the situation is represented by that formula.
